nervellns not postfurcal ; he adds that the extent of the rufescent 

 coloration is slightly variable, but the description I had drawn up 

 of the Bornean $ agrees entirely with that of his African spe- 

 cimens (Togoland and Senegambia). Van Yollenhoven did not 

 know the present species and merely conjectured it to be a 

 Rhyssa, allied to his B. laniaria, on account of its similar 

 coloration and terebral length. 



Brulle vaguely records the female from " les Indes orientales " ; 

 and I have described above another, which is in the British 

 Museum, bearing a pencil label : " Indrulaman, October, 1895 ; 

 H. H. Everett." I have seen the type of T. iiificeps, Cam., from 

 Kuching, Borneo, iu the British Museum, where also is another 

 female, taken at Mount Siban, Sarawak, in May, 1902. 



Meagre as is de Geer's description, it contains all the salient 

 points, I consider, for establishing the identity of Pimpla bipartita 

 with his Ichneumon rugogits, since he describes it: Of normal 

 size with abdomen strongly elongate ; bead red with the eyes 

 piceous ; antenna? broken ; thorax red. Abdomen subcylindrical 

 and a little broader centrally, rugose and black ; segments deeply 

 discrete with very remarkable discal rugosities and incisions, 

 rendering the surface uneven and rugose ; terebra as long as 

 the abdomen, with the spicula black and the valvulse stouter, dark 

 brown, apically obtuse and elongately pilose. Anterior legs red, 

 and the hind ones entirely black ; wings obscurely infumate 

 throughout, opaque, with a slight violaceous reflection. He says, 

 " J'ai lieu de croire que le senl individu que j'avois est originaire 

 des Indes." Olivier adds that it is 17 millim. in length, with the 

 antenna? black and shorter than the body ; and that it occurs in 

 Sumatra. Ket/ius simply quotes de Geer's diagnosis : but 

 Gravenhorst in 1829 thought it possibly identical with Ichneumon 

 (Ephialtes) instigator, Rossi (nee Fab.), which is incorrect; but 

 for lack of all later reference to it, Dalla Torre, in 1901, left 

 this species in Ephialtes, as inadequately described ; de Geer's 

 descriptions fortunately, however, very rarely fall into such a 

 category.

<$ $ . A large black species, with the head and thorax bright 

 red, and the wings flavescent. Head entirely red, transverse, and 

 strongly constricted behind the prominent black eyes ; occiput 

 abruptly declivous, glabrous, somewhat impressed laterally and 

 finely bordered posteriorly ; ocelli infuscate and elevated upon n 

 common plateau ; frons glabrous, with the scrobes large and 

 extending nearly to the ocelli ; face deplanate and flavidous, 

 with a few fine scattered punctures and rufescent hairs, centrally
